The evolution of the human oral microbiome is the study of microorganisms in the oral cavity and how they have adapted over time. There are recent advancements in ancient dental research that have given insight to the evolution of the human oral microbiome. [ 1 ]
The shifts in the oral microbiome through time have significant implications for modern health. The current lack of diversity in the oral microbiome makes it more susceptible to imbalances and pathogenic invasions. This, in turn, can lead to a range of oral and systemic health issues, from dental caries to cardiovascular disease.
In a study using Listerine Cool Mint, researchers concluded that alcohol-based mouthwash may disrupt a person's oral microbiome and lead to gum disease and certain cancers
Teeth, saliva, and oral tissues are the major components of the oral environment in which the oral microbiome resides. Like most environments, some oral environments, such as teeth and saliva, are abiotic (non-living), and some are living, such as the host immune system or host mouth mucosal tissues- including gums, cheek ("buccal") and tongue (when present).
Recent projects include "Dairying and Dietary Adaptive Evolution in Prehistory", "Evolution and Ecology of the Human Gut Microbiome" and "Evolution and Ecology of the Human Oral Microbiome". Research she led found the exotic mineral Lapis Lazuli in the plaque of a female skeleton found in a cemetery in Dalheim in Germany. A 2017 report detailed ...
The temperature and pH of saliva makes it conducive for bacteria to survive in the oral cavity. Bacteria in the oral cavity include Streptococcus mutans, Porphyromonas gingivalis, and Staphylococcus. [15] S. mutans is the main component of the oral microbiota. [15] A healthy oral microbiome decreases oral infections and promotes a healthy gut ...
The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, and the biliary tract.
The salivary microbiome consists of the nonpathogenic, commensal bacteria present in the healthy human salivary glands. It differs from the oral microbiome which is located in the oral cavity. Oral microorganisms tend to adhere to teeth. [1] The oral microbiome possesses its own characteristic microorganisms found there. Resident microbes of ...
